BigDecimal and BigInteger look like they would provide some rudimentary
support. Oracle's documentation doesn't show too much in the way of
functionality for typical experimental math support. Compare ARPREC
(http://crd-legacy.lbl.gov/~dhbailey/mpdist/) for example, from Bailey's page,
which uses the Fourier transform for digits > 1000, PSLQ, etc. So, it's not just
a matter of support for big numbers but performance tradeoffs and best
practices.
Anyway, without a Java library like ARPREC maybe I'll need to start with
BigDecimal and BigInteger and add on the other tools I need as well as
tweeking where needed. Maybe I could rely on GP to do the evaluation and use
BigDecimal and BigInteger as primitives. It should even be cleaner that way.
Thanks Warren for pointing out BigDecimal.
